Definitions

  • the present invention relates to a dental glass ionomer cement paste and a kit comprising the paste and a polycarboxylic acid aqueous solution. (Background technology)
  • Dental glass ionomer cement has excellent properties such as no pulp damage and better adhesion to tooth material than zinc phosphate cement. It is used for a wide range of clinical applications such as lining.
  • Glass ionomer cement is a reaction conjugate of an alkali earth metal-containing gate glass powder and an aqueous solution of a polycarboxylic acid.

  • the aqueous solution containing polycarboxylic acid is a copolymer of polyacrylic acid or acrylic acid and itaconic acid or maleic acid. Tartaric acid is added to an aqueous solution of the substance.
  • glass powder used for cement has a very active surface because it is in the form of fine powder, and easily absorbs moisture in the air and agglomerates. The use of such glass powder degrades the performance of the cement. In extreme cases, precautions must be taken when storing the powder, as it can stick to the container and render it unusable. is there.
  • the glass powder is a fine powder, and when taking out a predetermined amount of glass powder from the container, the dust may be scattered by the air inside and outside the room.
  • the present invention provides a paste for dental glass ionomer cement containing glass powder, a water-soluble polymer and water, and a dental glass ionomer cement preparation kit comprising the paste and an aqueous solution of a polycarboxylic acid. Is provided.
  • the specific surface area of the glass powder is usually 2.! ) To 4.0 irf / g.
  • Water-soluble polymers include methylcellulose and hydroxyp Mouth Cellulose derivatives such as pillmethylcellulose, hydroxymethylethylcellulose, hydroxyxethylcellulose and carboxymethylcellulose, polyvinyl alcohol and polyethylene glycol can be mentioned.
  • These water-soluble polymers can be used alone or in combination of two or more.
  • each component in the paste is in the range of 55 to 5% by weight of glass powder, 9.9 to 44.9% by weight of water, and 0.1 to 2.0% by weight of water-soluble polymer.
  • polycarboxylic acid polyacrylic acid, a copolymer of acrylic acid and itaconic acid, a copolymer of acrylic acid and maleic acid, and the like can be used.
  • the concentration of the aqueous solution of the polycarboxylic acid is preferably in the range of 40 to 75% by weight. If it is less than 40% by weight, the crushing resistance of the cured glass ionomer cement decreases, and if it exceeds 75% by weight, the viscosity of the liquid becomes high and the operability is deteriorated.

  • the molecular weight of the polycarboxylic acid is preferably in the range of 10 Q (! To 500 000, more preferably in the range of 200 Q (! To 100 000).
  • Organic acids such as tartaric acid, citric acid and ligonic acid can also be added.
  • an aqueous solution of a water-soluble polymer is prepared, and this liquid and glass powder are sufficiently kneaded with a mixer to obtain a uniform paste state.
  • any method can be used as long as it does not generate agglomerates due to poor dispersion of the glass powder, but a static mixer or an ultrasonic homogenizer is preferably used.
  • a dispersant to the paste.
  • dispersants polyethylene glycol, polyethylene glycol water-soluble resin, high molecular weight anionic surfactant, high molecular weight nonionic surfactant, ester nonionic surfactant, and ether nonionic surfactant Etc.
  • the amount of the dispersant added is preferably 0.5% by weight or less. 0.5% by weight
  • the ionomer cement breakage rate is high, which is not desirable.
  • a bactericide such as a positive electrode activator (benzyl type) and other scavengers used in conventional dental glass ionomer cement are added. Is also good.
  • the amount of the fungicide to be added is preferably 0.5% by weight or less.
  • the viscosity of the paste is, for example, appropriate for a toothpaste, and if it is below this range, powder and liquid may separate during long-term storage, and the amount of the curing liquid added later However, in order to maintain the viscosity of cement mud properly, it is reduced, and as a result, the physical properties of cement are reduced.
  • the paste of the present invention was prepared by sufficiently kneading 1000 g of the obtained glass fine powder and 3 OO g of a 2% by weight aqueous solution of methylcellulose with a static mixer.
  • the paste and the aqueous solution of polycarboxylic acid were placed in separate polypropylene syringes and sealed tightly so that they did not come into contact with air.
  • the paste and the aqueous solution of polycarboxylic acid were put out from a syringe at a weight ratio of 2.5: 1 onto a kneaded paper and kneaded for 30 seconds.
  • the coagulation time was 5 minutes and 30 seconds, but the kneading time was 1Z3, which is the same as that of the conventional Dallas Ionoma Co., Ltd. Wearing operation was also very easy.
  • the glass powder was in a paste form, the glass powder was not scattered by wind during kneading.
  • a paste of the present invention was prepared in the same manner as in Example 1 using the components shown in the following table, and mixed with a polycarboxylic acid aqueous solution.
  • the aqueous solution of polycarboxylic acid used in each of Examples 2 to 4 was prepared by the method described later.
  • the solidification time and operation allowance time are as shown in the table. All were excellent in kneadability. All cements required only about 30 seconds to train, and could be operated with sufficient margin. Further, the paste prepared in Example 1 was very excellent in storage stability.
  • the temperature of the reaction tank was set to 80 ° C, and the dropping tank 1 and the dropping tank 2 were simultaneously dropped in the nitrogen stream for about 2 hours. After the completion of the dropwise addition, the temperature was further maintained for 2 hours, and then the temperature was raised and refluxed for 3 hours.
  • the mixture was purified by steam distillation, adjusted to a concentration of about 65% aqueous solution by adjusting the concentration, and 180 g of tartaric acid was added.
  • the molecular weight of the obtained polymer in terms of polystyrene measured by gel permeation chromatography (GPC) was 53,700.
  • the glass powder is pasty, a metering device can be used and accurate measurement is possible. Since the glass powder is in paste form, kneading with the polymer aqueous solution is very easy, and kneading is completed in a short time, so that sufficient operation time can be obtained.

Abstract

Pâte pour ciment dentaire à base de ionomère de verre contenant du verre en poudre, un polymère soluble dans l'eau et de l'eau, et kit comprenant ladite pâte ainsi qu'une solution aqueuse d'acide polycarboxylique. Comme le verre en poudre se présente sous forme pâteuse, cette pâte présente les avantages suivants: 1) elle peut être pesée avec précision puisqu'un dispositif de décharge à vitesse constante est disponible, 2) elle peut être malaxée avec la solution polymère très facilement en un temps court de sorte qu'un temps de traitement suffisant peut être obtenu, 3) un mélange homogène peut être obtenu puisqu'il ne se produit aucune agrégation de la poudre du fait de l'absorption d'humidité, et 4) le local de traitement peut être maintenu propre puisque le verre en poudre ne se répand pas pendant le traitement.
